TILE-ARCH CONSTRUCTION.

Specification of Letters Patent.

Patented May 28, 1918.

Application filed April 26, 1917'. Serial No. 164,622.

To all whom it ma concern:

Be it known til at I, Jorm COMERMA, a subject of the Kin of Spain, and resident of the boron h of anhattan, city, county, and State 0 New York, have invented a new and useful Improvement in Tile-Arch Constructions, of which the following is a specification.

My invention relates to tile arch constructions for floors, ceilings and other building elements and has for its object to provide a construction of maximum rigidity and capable of sustaining heavy loads with safety. My improvement further contemplates a con struction in which the tiles develop a maxi-- mum resistance to transverse thrusts, compression strains and. to other forces which may occur in practice. Another object of my invention is to construct the tiles in such a manner that they may be readily ressed home in a bed of mortar or other bin or and so that a firm grip is obtained between the tiles and the mortar. In addition my improvement aims to provide a construction in which conduits or channels for the accommodation of reinforcing elements, electric wiring and the like may be readily formed. My invention will be fully described herein-- after and the features of novelty will be pointed out in the appended claims.

In the accompanying drawings, which show an example of my improvement for illustrative and descriptive purposes, Figure 1 is a cross-section of a tile arch constructed according to my invention; Fig. 2 is a detail section of another arch construction on an enlarged scale; Fig. 3 is a detail lan view and Fig. 4 is a perspective view 0 one of my improved tiles.

As shown in the drawings the tiles each comprise a main or body portion 5 provided at o posite edges with beveled surfaces 6 and as shown in Fig. 4. Each tile is further provided with a sin le rib 8 extending along one surface of the ody preferably in registry with the major median line thereof and in addition includes a pair of ribs 9 which extend along the other surface of said body and are preferably located at opposite sides of said major median line, in spaced relation to each other as illustrated in Fig. 4.

In utilizing my improved arch construction a first course of tiles 5 is laid upon a suitable temporary centering with the edges at which the beveled surfaces 6 and 7 are located, of adjacent tiles spaced from each other as shown in Fig. 2. The tiles 5 are laid with the single ribs 8 thereof projecting upwardly. A layer of mortar or other binder 10 is then placed upon this first course of tiles and between the adjacent ed es thereof after which a second course of ti es 5 is laid'upon the first course in the same way and also with the single ribs 8 extending upwardly. As shown in Figs. 1 and 2 the tiles 5 of the second course are laid in break-joint or staggered relation to the tiles of the first course or in other words so that the joints between adjacent tiles of the second course are in registry "with the single ribs 8 of the first course and with the spaces between the ribs 9 of the second course in registry with the joints between adjacent tiles 5 of the first course as shown in Fig. 2. The second course may now be again covered with mortar or other binder 10 after which a third course of tiles may be laid thereon, the arrangement of the tiles in the third cdursc corresponding to that of the tiles in the first course. l

This construction thus provides a break joint arrangement in a direction transverse to the arch. In the preferred form the tiles in the various courses are laid so as to also break joint in a direction longitudinally of the arch, for instance as shown in plan view in Fig. 3. It will of course be understood that the laying of the courses of tiles ma be continued in the same way until an arc of the desired thickness is secured.

The beveled edges 7 act in the nature of wedges and permit the tiles to be pressed home into the mortar or other binder with greater facility than if otherwise constructof mortar or other binder resist any tend-t- 100 ency of the tiles 5 in any course to move upward and provide what may be termed a mnimilnriy tho upper {URI}, ontvmri'lly. The arrangi ncni'. oi tho oindcr at tho points 11 in t i i also assists to n'cventi int" ca. 1 i1; iltiliii ibio to in i inning the i h c a rob, this being with. the ribs prow points 11 a z: mi mrnngo tiles in each course may actually abut or be .-a mced apart a sufficient distance to prevent tiw fornmtion of dry joints. It will, of course, bc ui'idumtocd that the number and rt-laiiw nrmngmcnt of tho ribs on the tiles may be other than that shown.

Various changcs in the specific form shown and. described may be made, Within tho soojvo of the claims Without departing Fioin the spirit of my improvement.

l claim:

L :m arch construction comprising it plulity of courses of tiles, projections of sub- Molly even dimensions throughout on 331d tiles extending into the joints between n-rijaccnt courses and givin a zig-zag form to said joints and a binder in said joints ex muting in zig-zag lines transversely to said arch.

An arch construction comprising tiles J in courses, in break joint arran ccinti vcly to each other, individual ribs *nntinlly even dimensions throughout c tending upwardly from the tiles in one no! me, a plurality of ribs of substantially :1! dimensions throughout extending Wmmrdiy from the tiles in the next uml'Sc, said ribs forming a zigzag joint beiw on said sources and a, binder in said joint intending in afiig-zag line tral'lsversely to gold arch.

S. An arch construction comFrising a course of tiles having individua ribs exi'fi-idllig upmmlly from and lengthwise of b tile, :1 second course of tiles having a 1 a of: (Ii-spending ribs spaced from each ot er nmf. extending lengthwise of each tile n d a o'.d course, the individual ribs i ii 'f; in asbstnntial register}; with the sub- 1 iiiiii) cortical joints of the second n'r rci and the space hetwcen each pair of de-gmmiing ribs; being in substzmtial registry ii iii] he :eubsmntinli vertical joints of the nod n binder in the joints bet on: not} tiles czztcnding in a, zig-zag lino it-w: namely of the arch.

L An arch construction comprism a plurality of superimposed courses of tiles, the 1 in adjacent com-50s being staggered wait to each Obi?? i11 ;.two directions, on on tiles of said adjacent courses dis jnrnnposcd relation to the joints {103011 in between tiles oi ut'ijaCtUt courses, thereby forming with tho titan zigzag joints extend mg transversely of said arch, and a binder aid joint.

An arch construction. comprising tiles 1-; ngcd in courses in break joint arrangem z 'itivcly to each otlicr, individual projwtions extending upwardly, from the Tito-1 in mm course, a plurality o projections on 2 3-1, n downwardly from the next course, 1 i m3 forming a, zig-zag joint bo- 1,907,747 w a a tween saidcourses and a binder in said 'oint tiles arranged to form diverging spades beextendin in a zig-zag line transverse y to tween adjacent tiles for the accommodation said are lower beveled surfaces at the of said binder.
